wifi: rtw89: rfk: disable driver tracking during MCC

After MCC (multi-channel concurrency) is started, FW will control channel
changes and use the corresponding backup of RF calibration result. And,
driver RF calibration (RF-K) won't be able to keep up with the speed at
which the channels are changing. So, even if we keep tracking it in driver,
the RF-K result might not be good either. To save these unnecessary things,
we disable driver RF-K tracking during MCC.
